Self-pogogoda wononga: izo uli ndi kumene applicable

Mtundu wa zinthu yolusa monga zomangira, ntchito kulikonse. Ndikovuta kulingalira zomwe iwo akhoza m'malo ngati n'koyenera. Chokhalitsa ndi pachimake fasteners yamazinga amalola mosavuta tili m'mavuto mu pamwamba pa zinthu za mitundu yosiyanasiyana ndi thicknesses. Wononga - sikuti ndi ndodo structural membala ndi ulusi kunja, nthawi zambiri ntchito kulumikiza kapangidwe zosiyanasiyana za zitsulo. m'madera onse a mtundu anawagawa kukonza ndi kusintha, malingana ndi njira ntchito.

Self-pogogoda zomangira ali ndithu chimagwiritsidwa ntchito kwambiri, iwo ntchito m'mafakitale ambiri, koma ambiri a fasteners izi mu ankafuna mu luso lopanga. Mkulu kumanga quality, otsika mtengo nthawi, chomasuka ntchito kuwonjezera kufunika kwa zomangira lapansi. Iwo akhoza tili m'mavuto mu aliyense, ngakhale kutali malo, ntchito mtedza ndi Sikuti. Komanso, si koyenera kuti dzenje, mwachindunji pa msonkhano aumbike paokha.

Nthawi zambiri kudziletsa pogogoda wononga umagwiritsidwa kwa kulumikiza nyumba yopangidwa ndi zisulo monga mpweya zitsulo otsika, kasakaniza wazitsulo zotayidwa ndi mkuwa ndi pulasitiki. Kuyambira dzina, si kudziyesa kuti wononga akhoza kudula zakuthupi, amene zikugwirizana. Mwina chifukwa mapindikidwe pulasitiki ndi kukanikiza mu chitsulo kapena mapulasitiki.

Mfundo GOST 1478-93 ndi GOST 2702-93 nthawi amasokoneza ake ndi luso yopanga. Zofunika pa zomangira kanasonkhezereka ndi countersunk chowulungika mutu ndi mu mawonekedwe onse. Zomangira komanso zilipo ndi kuchuluka kwa Phillips ndi mutu yamphamvu. Self-pogogoda wononga ali kwambiri mitundu ina kuposa tazitchula, zimapezekanso ndi mutu mphako, flange, nyenyezi-ceni. Komabe, otsiriza zomangira atatu la Russia si ntchito, chifukwa iwo alibe mfundo. Ngakhale pamene izo zifika kumanga quality, ali kwambiri mwapang'onopang'ono kuposa zomangira muyezo.

Self-pogogoda wononga, thupi limodzi la mtundu watsopano, si ntchito yopanga Russian. chifukwa lagona mu disparity pakati pa kukula kwa ulusi. chakuti fasteners helical ndi, mphako mutu nyenyezi lotengeka ndi flange, ngakhale kuposa zoweta, koma ali ndi ulusi chosiyana. Komanso iwo alibe zizigwirizana panopa chomveka mfundo zitatu lolamulira amasokoneza ndi luso yopanga. Kapangidwe ndi kukula kwa zomangira osati mogwirizana ndi miyezo Russian.

International Standard ISO 1478-2005 kale anagula mtundu watsopano, zokhudza kupanga komanso kugwiritsa ntchito zomangira ndi mapeto anamaliza. Mwina posachedwapa ndi kudzikonda pogogoda wononga chidzaonekera Russia, ndiponso kutenga mfundo yoyenera. Kuyambira kalekale anthu akhala anakonza kusintha mfundo zonse Russian kutsatira mfundo lonse.

Posankha kapangidwe wononga n'kofunika kuyamba nkhani ndi zimene zimafunika kogwirizana, wochindikala ndiponso kuya kofunika una. Malinga mtundu wa Kuphunzira, ndi zomangira zonse kudziletsa pogogoda anawagawa kanasonkhezereka, electroplating ndi wakuda.
